If the IED detects an error it displays an error message, logs amaintenance record and after a short delay resets itself. A permanent problem (for example due to a hardwarefault) is usually detected in the power-up sequence. In this case the IED displays an error code and halts. If theproblem was transient, the IED reboots correctly and continues operation. By examining the maintenance recordlogged, the nature of the detected fault can be determined.P24xM Chapter 20 - Maintenance and TroubleshootingP24xM-TM-EN-2.1 425
